SAN FRANCISCO (CBS SF) — A portion of Interstate Highway 280 in San Francisco reopened Sunday evening after being closed for construction during the holiday weekend, Caltrans officials said.

Northbound Highway 280 closed from the U.S. Highway 101 interchange to downtown San Francisco around 9 p.m. last Wednesday and reopened at about 7 p.m. Sunday night, roughly 10 hours ahead of schedule, according to Caltrans.

During the closure, crews worked to replace a bridge hinge on northbound Highway 280 between Cesar Chavez and 24th streets.

The bridge hinge connects two parts of a bridge to expand and contract during earthquakes and other strong movements, according to Caltrans. Another closure to complete work on the bridge hinges is planned for the Labor Day holiday weekend.

Motorists during this weekend’s closure were unable to use highway off-ramps including Mariposa Street, Sixth Street and King Street.
